It appears that Toyota has been busy developing their B-segment stalwart. A forum member from Headlight Magazine Thailand spotted what appears to be the next-generation Vios. Still heavily camouflaged, a few design details can be seen upon closer inspection.

Also photographed was the Vios' hatchback counterpart, the Yaris. The covers on both cars suggest that these will either be all-new models or an extensive redesign of the current model. By the looks of it, the Vios and Yaris appear to have adapted the 'Keen Look' design language that was set by the Corolla Altis.

In the case of the Yaris, we see large headlight units that stem from the grill and extend all the way to the fender. Also seen here are foglights complemented by a sweeping piece of trim at the corners of the bumper. A large air intake is also present. Given that the current models have different front fascias, expect the Vios to have its own front fascia design.

Back to the Vios, it now features a different, if slightly curvier, roofline. The window line meanwhile now has a gentle upward sweep, unlike the current model's flatter line. A closer look at the door sees two defining character lines, one of which forms the car's shoulder line. Toyota Thailand went as far as putting camouflage on the wheels, hinting all-new designs for the B-segment sedan.

The rear photos of both the Vios and Yaris paint a clearer picture of what the two might look like. In the Vios, we see a wider stance, thanks in part to the shoulder line. The trunk opening has also been widened. Its tail lights meanwhile appear to be slimmer than the current model's units. On to the Yaris, the tail lights have been made larger and the tailgate and bumper are noticeably rounder.

Engine details have yet to be determined. Given that the current Vios and Yaris received new Dual VVT-i units in their updates, it is likely that these will be carried over to the all-new or heavily revamped models. The forum reported that the all-new Vios will be revealed in Thailand later this year with the Yaris following a new months later.
